Wide Input SHIM lets you use a range of different DC power supplies with your Pi, including the ubiquitous 12V barrel jack power supplies. It's super-skinny, so you can solder it straight to your Pi's pins and still use HATs and pHATs on top.

The barrel jack connector on Wide Input SHIM is a 3.5mm outer diameter (OD), 1.3mm inner diameter one, and there's a short male to female adapter cable included to allow you to use the common 5.5mm OD barrel jacks too.

There's also a short cable included with a 3.5mm OD barrel jack on one end and tinned wires on the other, in case you want to attach it directly to something like a bench power supply or to solder it into a project.

If you need a longer power cable, then there's a 1.5m long 3.5mm OD male to tinned wires cable available separately.
